Bubblegum popster Justin Bieber told reporters who attended a London preview for his third studio album that one of the tracks he wrote for Believe is about "that girl - Mariah Yeater - who said she was going to have my baby."

The announcement comes mere days after Bieber took to Twitter to pen a left-field tweet prodding "Yeeter" with a link to an audio clip of Borat saying "you will never get this."

Bieber said of tracklist for Believe (due in stores June 19): "There are songs about things I'm going through. I wrote songs about different situations." He went on to add that the Yeater song might not appear on the album, saying "We've recorded like 40 songs. Every song has a piece of me, it's hard to pick."
